Skin Idea - Disguise skins

So, i had a cool idea which i pitched to a couple of friends for a load of skins for various champions.

I thought that having skin mashups would be an awesome idea, such as Poppy dressed up as Blitzcrank, Or Ahri dressed up as Teemo, and so on. Obviously the skins would still have to be visibly obvious it's the actual champion you're playing, to avoid confusion in game. But i just thought this would be an awesome thing to have.

What's everyone else views on this? is it an idea you'd like to see integrated into the game? what champions would you like to see dressed up as another?
